TYPE-WRITING IVIACHINEl SPECIFICATION forming* part Of Letters PatentN0. 674,967', dated. May 28, 1901. Application filed December 20, -l99|Serial No. 741,035. (No model.)

To @ZZ whom, t 71mg/ conoci/'7o.-

Be it known that I, JOHN JAY GREEN, of Boonton, in the county of Morrisand State of New Jersey, have invented certain new and usefulImprovements in Type-Vriting Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as Will enable others skilled in the art to which it appertains tomake and use the same. 1

My invention relates to an improvement in type-writing machines, andmore particularly to such as are known in the art as indexwheelmachines, one object of the invention being to minimize the number ofconstituent parts of a type-Writing machine and reduce the cost ofmanufacture Without detracting from the efficiency of the machine, but,on the contrary, enhance its capacity, ease of manipulation, and itseffectual execution of the functions required of a modern type-writingmachine of the index-Wheel type.

A further object is to so construct a typewriting machine of theindex-wheel variety that a notched wheel shall cooperate With thetypecarrier and manipulating devices in such manner as to assist inpositioning the letters and then serving to positively lock thetypecarrier in writing position.

A further object is to so construct a typewriting machine thata notchedlocking-Wheel can be employed Ahavinga numberof notches, which shall beequal to a part of the number of type characters.

A further object is to construct a simple and comparatively inexpensivetype-writing machine in such manner that the writing shall be plainlyVisible during the operation of the machine.

A further object is to so construct and arrange a notched positioningand locking Wheel for the type-carrier that the Walls of each notch.will so coperate with actuating devices as to position and lock severaldifferent printing characters, according to the key-bar depressed by theoperator.

A further object is to provide simple and e'iicient shifting devices forupper-case char-l acters.

With these objects in View the invention consists in certain novelfeatures of construction and com binations and arrangements of parts, ashereinafterset forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan View of a type-Writingmachine embodying my improvement. Fig. 2 is a plan view with some partsremoved and other parts shown in section. Fig. 3 is a similar view Withadditional parts removed. Fig. 4 is a side elevation. Fig. 5 is atransverse sectional vieW. Fig. 6 is an end view of the carriage. Fig. 7is a transverse sectional View of the carriage. Fig. S is a detail Viewof devices for locking the parts against operation When the carriageapproaches the end of'its travel. Figs. 9 and 10 are detail Viewsshowing the positioning and locking devices for the type-carrier. Fig.11 is an enlarged detail view of the carriage ratchet feed device. Fig.12 is a detail view of a portion of the locking device shown in Fig. S.Figs. 13, 14, and 15 are views illustrating certain other details ofconstruction.

The main frame of the machine comprises a fixed base l, made in a singlecasting, and a top piece 2, supported by posts or uprights 3 and bracedby integral brackets 4. The base is mounted on suitable legs or supports5. The brackets 4 at the inner end of the machine serve to support apivoted frame 6, said frame having at its inner end upwardlyprojectingears 7, pivotally attached to said brackets. The pivoted frame comprisesa front bar 8, a rear bar 9, of greater length than the front bar, andparallel arms 10, spaced apart and connecting the bars 8 and 9 at pointsbetween their inner ends, and the intermediate portion 11 of the rearbar 9 is curved rearwardly for a purpose hereinafter to be explained.From the respective ends of the rear bar 9 of the pivoted frame arms 1212 project rearwardly and are secured to or made integral with a trackor rail 13 for the accommodation of the carriage 14. VThe intermediatebar 15 of the carriage is provided with rollers 16, mounted t0 run onthe head of the rail 15, and also With notched lugs 17 to receive saidrib and preventlateral play or displacement of the carriage. The innerbar 18 of the carriage extends from end to end thereof and is disposedabove the arms of the pivoted frame. To the inner har 18 a ratchet-bar19, having teeth on its upperedge,

TOO

its center.

is secured. v"Iwo plates 20 are removably secured to the pivoted frameand project at their rear edges partially over the ratchetbar 19 toprevent vertical displacement of the carriage. To render the platesreadily removable without completely withdrawing the screws 21, they areprovided with elongated slots 22, through which said screws pass. Therear bar 23 of the carriage is mounted in a slot 24 in the upper end ofa post 25, disposed on the curved intermediate portion l1 of the pivotedframe. By mounting the carriage as above explained its easy removal canbe effected by loosening the screws 21, swinging the plates 2O fromunder the heads of said screws, and then lifting the carriage 'from itsbearings. A platen-roller 26 is mounted at its ends in the ends of thecarriage and cooperates with various devices hereinafter to be describedfor effecting the feed of the paper.

The pivoted frame is maintained normally in the position shown in Figs.4 and 5 by means ofa spring (or springs) 27. The spring 27 is made inthe form of a hook or open loop and is secured at one end to one of theuprights of the rigid frame at the inner end of the machine, the otherend of said spring bearing against the pivoted frame at a point belowthe fulcrum thereof.

Two short posts 28 29 project upwardly from the rigid base 1, near therear portion thereof, and between said posts a carrier frame 30 ispivotally supported rearwardly of The rear end of the carrier-frame ismade with an enlargement 31, which serves as a counterbalance for saidframe and the parts carried thereby. A rod or shaft 32 is rigidlysecured to the carrier-frame at a point inwardly from the fulcrum ofsaid frame and projects upwardly some distance. Surrounding the rod orshaft 32, throughout the greater portion of its length, is a sleeve ortube 33, of brass or other suitable material. A type wheel or carrier 34(having three rows of characters) is mounted on the brass sleeve 33 atvthe upper end thereof, and below said typecarrier an aluminium sleeve 35is mounted to rotate with the brass sleeve or bushing 33. An arm 36projects outwardly from the upper end of the sleeve 35 and is connectedwith the type-wheel by means of a pin 37, as clearly shown in Fig. lO.The inner end of the carrier-frame 30 is made with a standard 38, whichprojects upwardly to a point slightly above the plane of thetype-carrier, and to the upper end of said standard au approximatelyhorizontal arm 39 is pivot-ally connected. The free end of the arm 39 ismade with a notched lug 40, which serves as a sight or indicator toassist the operator in locating the point of writing on the paperpassing over the platen-roller, and thus enable him to make correctionsand insertions accurately. The arm 39 is made near its free end with aperforated boss 41, into which a thimble 42 is inserted, and into thelower portion of said thimble the upper end of the rod or shaft 32projects. The bore of the thimble is threaded for the reception of thethreaded upper end of the shaft 32 and a small screw 43, which normallybears at its lower end against the upper end of said rod or shaft.

From the construction and arrangement of parts above describedit will beseen that the shaft on which the type-wheel is mounted is supported atboth ends and that when the carf` rier-frame 30 is moved to throw thetype-wheel against the paper said supports will move in unison, and thusprevent lall possibility of strain on the shaft 32, and in this wayinsure the continual accurate operation of printing devices.

An aluminium wheel 44 is made integral with thelower end of thealuminium sleeve 35 and is provided in its periphery with a groove 45for the accommodation of a cord or chain 46. A ring 47, having teeth orprojections,

is secured to the under face of the wheel 44` and depends therefrom,said wheel having ten large teeth, and each tooth is made with bevelededges, the adjacent edges of two teeth cooperating to forminverted-V-shaped notches.

The wheel 44 is maintained in and returned to its normal position bymeans of a convolute spring 48, one end of which is secured to the hubof the wheel and the other end to the pivoted carrier-frame 30, and saidwheel 44 is operated and controlled for the purpose of rotating thetype-wheel to position the characters thereon by means of devices thedetails of which will now be explained ln front of the framework aseries of keybars 49 is disposed, each provided with a series ofcharacter keys or buttons 50. I prefer to employ three key-bars 49 andto secure ten character keys or buttons 50 to each keybar, as shown inFigs. 1, 2, and 3. Each keybar is provided with an arm 51, whichprojects over the base-frame 1 and pivotally supported near its end to alug 52 on said base, as shown in Figs. 3 and 15. provided with lugs 53,disposed alongside the arms 51 to prevent lateral displacement of thesame and of the key-bars. In rear of each arm 51 the base l is made withahole 54, and in rear of said hole a lug depends from the under face ofthe base, as best shown in Fig. 15. One end of a spring 55 is passedthrough the hole 54 and is made with a perforation to receive the lug.The other end of each spring is located under and exerts an upwardpressure against the arm 51 of one of the key-bars for the purpose ofholding said key-barsin and returning them to their normal positionafter having been depressed.

Levers 56, 57, and 5S are pivotally supported between their ends bymeans of lugs located near the inner edge of the base 1 and areprevented from lateral displacement by means of lugs 59 on said base.The inner ends of the levers 56 57 5S are secured, respectively, to thekey-bars 49, and at their other or rear ends they are provided withhori- Zontal arms 60, 61, and 62, respectively, said IOO IIO

The base 1 is arms being preferably disposed in a line parallel with ahorizontal line drawn transversely through the shaft 32,011 which thetype-wheel is mounted. Behind the shaft 32 a fixed shaft 6l is disposedand held between two lugs on the pivoted carrier-frame 30. (See Fig. 9.)Three sleeves 62 are mounted loosely on the shaft 61, and from saidsleeves arms 63 64 65 project toward the front of the machine anddirectly over the arms 6l 62 of the levers 56 57 58, so as to beactuated by the latter. Springs 66, Fig. 9, may be secured to the levers56 57 5S and adapted to act as a cushion between the arms thereon andthe arms 63 64 65. The free ends of the last-mentioned arms are bentinwardly and provided, respectively, with dogs or enlargements 67 66 69,disposed under the toothed wheel 47 and adapted to coperate therewithfor positioning the type-wheel. The type-wheel is rotated by themovements of the hand of the opera-tor through the medium of the cord orchain 46. This cord or chain is secured to and wound in the groovedperiphery of the wheel 44, and from said wheel it passes over a pulley70, mounted on the enlarged end of the pivoted carrier-frame 30, thencearound a pulley 7l, mounted on a pivoted arm 72, and provided at itsfree end with a leather loop 73 for the reception of the index-linger ofthe operator. The loop 73 is preferably provided with a movable ring orferrule 74 for the purpose of adapting the loop to the finger of theoperator. The arm 72 above referred to is provided at one end with afixed sleeve 75, mounted loosely on a post projecting upwardly from thebase l, and from the lower end ot' said sleeve a short arm 76 projects,as shown in Fig. 13. The short arm 76 is provided with a lug or tooth 77for the attachment of one end of a spring 78, the other end of which isattached to the base l. The arm 72 is thus pivotally and yieldinglyattached to the base and serves to prevent undue strain on the cord orchain, the toothed wheel, and the devices cooperating with the latter. Aspring-plate 79 is secured to the free end of the arm 72 and projectsover the pulley 7l, so as to retain the latter in place and serve as aguide for the cord or chain i8. The free end of the spring-plate 75l ismade with a teat 8O to engage a notched boss 8l on the arm 72. A lug 82is cast ou the base l adjacent to the short arm 76, and through thisluga horizontal thumb-screw passes, the free end of said screw abuttingagainst a lug 83 on said arm 76. By these means the normal position ofthe arm 72 can be readily adjusted. Theinward throw of the pivoted arm72 is limited by the engagement of a lng 84 on the short arm 76 with thelug 'lhe operator will place the loop on his index-linger and then movehis finger to desired characterkey. In performing these movements thecord o1l chain 46 will be pulled and the grooved wheel rotated to movethe type-wheel to bring the desired letter to or approximately toWriting position. The operator will now depress the key and, assumingthat it is one of the keys on the central key-bar, motion will betransmitted to the central lever 57, and the latter will raise the arm61k and cause the dog or enlargement 68 at the free end thereof to entercentrally between twb teeth of the toothed ring 47 and become disposedat the juncture of the adjacent. edges of said two teeth. Should theoperator depress the key-bar nearest the machine-frame, the lever 56will be operated and the arm 63 raised, so as to cause the dog orenlargement at the free end thereof to enter a notch between two teethand engage a beveled edge of one of the teeth forming said notch at apoint between theends of said beveled edge. The pressure of the dog orenlargement 67 against the beveled edge ot' the tooth ofthe ring willact to turn said ring slightly farther than it was moved by the cord orchain to accurately position the type-wheel for the desired letter.'lhis additional movement of the toothed wheel will continue while thedog or enlargement 67 is moving along the beveled edge of a tooth, thearrival of the dog or enlargement 67 at the angle formed by the junctureof the beveled edges of two adjacent teeth insuring the properpositioning of the type-wheel for the desired letter.

Should the operator depress the key-bar farthest removed from themachine-frame, the operations would be similar to those just described,the toot-hed wheel in this case being actuated through the medium of thelever 58, arm 65, and the dog or enlargement 69 on said arm, the dog orenlargement engaging a beveled edge of a tooth at the righthand side ofthe notch between two teeth iustead of at the left-hand side, as was thecase with the dog or enlargement 67 on the arm 63, and thus theadditional movement imparted by engagement ot' the dog 69 with thetoothed wheel will be in a direction opposite to that imparted by thedog 67.

From the above description it will be seen that when the inner or outerkey-bar is operated a slight additional movement will be imparted to thetype-wheel in one direction or the other, according to the key-bar whichis depressed.

If the internxediate key-bar is accurately operated, no additionalmovement will be imparted to the type-wheel; but should the operator notpull the cord quite far enough or slightly too far the dog on theintermediate arm 64 will engage the edge of a tooth at one side or theother ol" the notch formed by t vo teeth, and thus cause the wheel tohave a slight additional movement. to accurately position the desiredletter.

It will be noticed that the dogs 67 68 69 engage tho toothed wheel at apoint some distance inwardly from the Fulcrum ot' the earrier-frame 30,so that after the type-wheel shall have been set for writing positioncontinued pressure on a key-bar will cause the TOO ' and enters thecarriage-frame.

carrier-frame to be tilted and the type-wheel' to be thrown toward theplaten-roller for the purpose of printing upon the paper passing oversaid roller.

The inking-ribbon 85 is attached to and moves with the platen-carriage14 and is supported and guided by means of devices which will now bedescribed.

At respective ends of the carriage plates 86 are loosely mounted betweentheir ends on the journals of the platen-roller, one of which journalsis mounted in a hole in one end piece of the carriage and the otherjournal is mounted in an open slot 87 in the other end piece of thecarriage. The rear portion of each plate 86 is made with an open slot88, through which a screw 89 passes The rear ends of the plates 86 areprovided with hori- Zontal pintles 90, on which ribbon-reels 91 aremounted and provided with knobs 92 for turning them to run the ribbonfrom one reel to the other. Spring-tongues 93 bear against said reelsand normally prevent them from turning and also serve to prevent theirdis placement. The inner ends of the plates 86 are bent laterally andthen inwardly toward the front of the machine to form arms 94, and eachof these arms is made with an open slot 95, having one wall beveled toform a shoulder 96. The inking-ribbon is guided through the slot-s 95and becoming disposed under the shoulders 96 will be prevented fromupward displacement. By mounting the ribbon-carriers as above explainedit will be seen that they can be readily removed, together with theplaten-roller, by merely loosening the screws 89, and it will also beseen that by the connection of the plates 86 with the carriage by meansof the screws89 displacement of the platen-roller will be effectuallyprevented.

Inking-rollers 97 are mounted on the rear bar 9 of the pivoted frame 6at respective sides of the space through which the typewheel passes forthe purpose of keeping the ribbon supplied with ink. These inkingrollersare important,because,as above stated, the ribbon moves with thecarriage, and if some means for replenishing the ink to the ribbon werenot provided the latter might become inefficient after a number of linesshall have been written. The ribbon will be made of a length severaltimes that of the carriage, the surplus being wound on one or the otherof the reels. When a section of the ribbon shall have become worn out,the operator will wind it on one of the reels and simultaneously unwinda fresh section of ribbon from the other reel. .The ribbon will bemaintained normally taut and away from the platen, so that the writingwill be always visible, by means of a spring-actuated arm 98, carrying aroller 99, over which the ribbon passes, and by means of which theribbon will be forced against the inking-rollers.

The paper is conducted to the platen-roller by means of a sheet-metalguide-plate 100.

The guide-plate is secured to the rear bar of the carriage by means oftongues 101 and projects downwardly under the platen-roller,

vterminating at a point somewhat beyond the axis of the roller, where itis provided with ears which constitute bearings for a feed-v roller1.02. The feed-roller is pressed against the platen-roller by means of aspring 1037 secured to the carriage and pressing upwardly against thesheet-metal guide-plate 100. To move the feed-roller away from theplatenroller to permit the free adjustment of the paper a lever 181 maybe employed. The paper is pressed neatly against the platenroller at thecenter by means of a V-shaped loop 104, having arms 105, secured to thepivoted frame 6. The loop 104 partially embraces'the platen-rollerand-holds the paper or au envelop closely against the roller at thepoint of writing, the characters on the typewheel passing through saidloop when said wheel is thrown forward during the operation of themachine.

Y For the purpose of feeding the paper one end Yof the platen-roller isprovided with a knob`105, and for the purpose of accurately regulatingthe line-spaces a ratchet device now to be described will be employed. Aspur-wheel 106 is secured to a journal of the platen-roller and isadapted to be engaged by a tooth or shoulder 107 on a spring 108. Therear end of the spring 108 is provided with an arm or flange 109,attached to the carriageframe, and said arm or flange is made with abeveled end which rests ona shoulder or enlargement 110 on the carriageto insure the maintenance of proper tension of the spring. When it isdesired to move the paper without regard to the line-spacing, (as when asheet is inserted for the purpose of making insertions or corrections,)the tooth or shoulder 107 should be moved out of contact with thespur-wheel. For this purpose an arm 111 is loosely mounted on a journalof the platenroller and is provided with a notch 112 for the receptionof the tooth or shoulder 107, as shown in Fig. 6. It is apparent thatwhen the arm 111 is moved toward the end of the spring the shoulder atthe lower end of the notch in said arm will engage the beveled end ofthe tooth or shoulder 107 and cause said tooth or shoulder to rise outof engagement with the spur-wheel and its free end to enter the notch112, thus releasing the platen-roller and permitting it to be turned tofeed the paper irrespective of the line-spacing.

With the parts of the machine in their normal position, as shown in thedrawings, the platen-roller is in position to permit the printing of thelower-case characters, which constitute the upper row of type on thetypewheel. To permit the printing of characters and figures of the twolower rows of type, the platen-roller must be lowered, as is evident,and for this purpose the appliances now to be explained will beemployed.

A sleeve 113 is loosely mounted between IOO IIO

two lugs 114, projecting upwardly from the base l, near the rear endthereof, and from said sleeve a lever projects toward the front of thebase, said lever being provided at its front end with an arm 116, whichprojects laterally beyond the machine-base, said arm being so bent as iocause the outer portion 119 thereof to be disposed on a higher planethan the inner portion and than the lever 115. The lever 115 isconnected with the pivoted frame 6 by means of a link 118, so that whensaid lever is depressed the pivoted frame carrying the platen-rollerwill be lowered. To afford ready ad just-men t for the pivoted frame 6and to maintain it in such position as to insure the maintenance of theaccurate normal position of the platensroller for lower-case characters,the sleeve 113 is provided with a rearwardly-projecting arm 119, throughwhich a set-screw 120 is passed and adapted to rest on the base-frame 1.Il is apparent that by adjusting this screw the normal elevation of thepivoted frame and platen-roller can be easily regulated.

'lwo ears 121 project upwardly from the base 1 in rear of the arm 116and to one side of the lever 115. Between these ears the ends of a shaft122 are secured, and upon said shaft two sleeves L3 124 are looselymounted. From the respective sleeves 123 124 key-levers 125 126 project,one of said levers being provided with a key 127, indicating capitalletters, and the other lever being provided with a key 128, indicatingfigures, the key 127 having the letters Cap thereon and the key 128having the letters Fig The upward movement of the key-levers 125 126will be limited by the engagement of lugs 129 on the sleeves with theears 121. The two key-levers 125 126 project directly over the elevatedportion 117 of the arm 116, and the lever 125 is provided between itsends with a lug 130, thron gh which a vertically-disposed screw 131passes. The screw 131 is adapted to engage the upper end of a post 132on the base 1 for the purpose of limiting the downward movement of thepivoted frame 6 and platen-roller when the key 127 is depressed, andthus dispose the platen-rollerin position for printing capitals. Forprinting iigures the platen must descend still farther, and for limitingthe downward movement ofthe pivoted frame 6 when the key 12S isdepressed a lug 133 on the pivoted frame 6 is adapted to engage anadjustable screw at the upper end of a post 134 on the base 1.

Having described the construction and operation of the printingmechanism and the devices which coperate therewith, I will now proceedto explain the manner of el'ecting and controlling the feed of thecarriage.

A spring-actuated drum 135 is mounted on the rigid frame of the machine,and around this drum a cord 136 is wound, the free knotted end of saidcord being attached to a notched arm 137, project ing from a plate 138,scoured to the carriage.

A rocking bar 139 is disposed transversely on the pivoted lframe andprovided on its under face near one end with a depending lug 140, towhich the spacing devices are connected. These comprise a plate 141,having ears 142 at one end, pivotally attached to the lug on the rockingbar, and providedi at its oiher end with a flange 143, the outer end ofwhich constitutes the fixed dog 144 to engage the ratchet-bar 19 on thecarriage. A spring 145 is attached at one end to a lug depending fromthe plate 141 and at its other end to the pivoted frame 6. A plate 146is pivoted at its inner end to the plate 141, and at its outer end it isprovided with a`iiange 147, which projects beyond the outer end of theplates 141 and 146, and is provided' in its lower edge with a notch 148,the portion of the ange beyond said notch forming a tooth 149 to engagethe ratchetbar 19. -The plate 146, with its notched flange and tooth,constitutes the movable dog of the ratchet feed devices. The plates 141 and146 are connected together beyond their pivotal connection by means of aspring 148` The anges of the plates 141 and 146 are disposed between andguided by lugs 152 on the pivoted frame.

The rocking bar 139 is provided with an upwardly-projecting arm 149, towhich one end of a rod or wire 150 is attached, the other end of saidrod or wire being connected with a stepped lever 151,:di'sposed underthe keylevers and adapted to be operated by the same when they aredepressed. When a key-bar is depressed, motion will be transmittedthrough the lever 151 and rod 150 to the rocking bar 139, thus causingthe latter to rock and force the plates 141 and 146 forwardly. Theresult of these movements will be to cause the xed dog on the plate 141to engage a tooth of the ratchet-bar 19 and the pivoted dog to move outof engagement with said ratchet-bar. When the key-lever is released, thebar 139 will rock in the reverse direction, and thus move the fixed dogont of engagement with the ratchet-bar and the pivoted dog intoengagement with a new tooth on said ratchet-bar, thus permitting thecarriage to feed a distance of one tooth.

An independent spacing-lever 153 is disposed alongside the stepped lever151,and the latter is made of such length as to be disposed under thefinger-key 154 on said spacing-lever, so that when the latter isdepressed motion will be imparted through the devices above described tolthe ratchet feed mechanism for the purpose ot' eifecting the feed ofthe carriage for spaces between words. The spacing-lever 153 is carriedby a sleeve 154, mounted between lugs on the base 1. The

,sleeve 154 is provided with an arm 155, to

which one end of a spring 156 is attached, the other end ot' said springbeing connected to IOO an arm 157 on the base 1 for the purpose ofreturning the spacing-lever. The upward 'movement of the spacing-leveris limited by the engagement of an arm 158 on the sleeve 154a with thebase 1.

For the purpose of releasing the ratchet feed mechanism when it isdesired to move the carriage freely I Yemploy a rod or wire 159,disposed on the carriage under the dogs of the ratchet mechanism. Theends of the rod or wire arebent to form loops 160, which serve ashandles, and the free extremities of said rod or wire are bent to formpintles 161,

" .pivotally mounted in the ends of the carriage.

In View of the bell usually employed for denoting the approach of theend of travel of the carriage I prefer to employ devices for positivelylocking the feed mechanism of the carriage, and these means will vnow bedescribed. An arm 162, comprising a member 163 .and a member 164, ispivotally attached at the juncture of said members to the pivoted frame6. A finger-bar 168, made integral with the member 164projects therefromand is provided at its free end with a fingerkey 169. The free end ofthe member 164 of arm 162 is made with an upwardly-projecting tooth 165,and the free end of the member 163 terminates normally to one side of alug 166, depending from the rocking bar 139, in which position it isretained by means of a spring 171. The plate 138, hereinbefore referredto, attached to the carriage, is made with a series of two or morebeveled teeth 167 and with a notch or recess 170. With this constructionand arrangement of parts when the carriage approaches the end of itstravel the tooth 165 at the end of member 164 of arm 162 will ride uponthe first beveled tooth 167 on the plate 138, and thus cause said arm162 to turn on its fulcrum and the free end of the member 164 thereof tobecome disposed in line with the depending lug 166 on the rocking bar139. This will lock the rocking bar against movement, and said rockingbar being actuated by the key-bars through the medium of the lever 151and rod 150 these parts will also be locked, so that when the member 163of the arm 162 is in line with the lug 166 the keys, as well as therocking bar, will-be locked and the further operation of themachine willbe positively prevented. Should it be desired, however, to permit a fewmore letters, this may be accomplished by moving the arm 162 by means ofthe finger-bar 168 and permitting the carriage to move one tooth, whenthe tooth 165 on-the member 164 of said arm will become disposed betweentwo teeth 167 on the plate. The carriage can now feed several spaces anduntil the parts again become locked by the engagement of the tooth 165with the second tooth 167 on plate 138. The parts may be again releasedin the manner above explained to permit the insertion of additionalletters, after which the tooth 165 will ride into the notch 170 of plate138 and the further feeding of the'carriage will be absolutelyprevented. The carriage can be moved one space farther by the hand andone letter printed by the operator manipulating the carriage-releasekey.

It now remains to describe the manner of regulating the margin to beleft at the edge of the paper.

A horizontal bar 172 is mounted to Slide through a transverse hole nearthe base of the port 125 on the curved intermediate portion ofthepivotedframe'6,a11d said rod also passes through a perforated lug 173 toprevent pos"- sibility of lateral displacement. A ratchetbar 174(preferably of sheet metal) is provided at its ends with ears or arms175, loosely attached to the ends of the bar 172. An elongated tooth 176is provided on the post 125 and adapted to engage the ratchet-bar 174 toretain the latter at any desired adjustment, and the ratchet-bar ismaintained in' contact with said tooth by means of a spring 177, securedto the frame. One end of the ratchetbar is made with a shoulder 178,against which the enlargement 110 on the carriage abutsto limit thereturn movement of the latter, and thus regulate the margin. One end ofthe ratchetbar is provided with a thumb-piece 179, by means of which tomanipulate and adjust the same, and the backward movement of theratchet-bar may be limited by means of an arm 180, fixed to the pivotedframe.

It will be observed that with my improved machine the writing is alwaysclearly visible. A small number of parts is employed as compared withother machines of which I am aware, my improved machine comprising onehundred and fifty separate pieces as against one thousand to twothousand five hundred constituting other machines. It is simple inconstruction, easy to operate, and it is accurate in the performance ofits functions'.
